Introduction to Qiuzi Cave: There is a virgin forest in the upper reaches of Cuogao Lake. Walking along the creek towards the hillside, you can see that the trees in front are covered with prayer flags and strips of hadas, and there is a shape like female genitalia on the rock. . Local people say that this is a natural phenomenon. If a couple does not have children, if they burn incense and pray here, the gods will bless them with a child.
